Description

Technical Field

[0001] This invention belongs to the technical field of oil pipe bending equipment, and relates to a bending and forming equipment for the return oil pipe of an engine turbocharger. Background Technology

[0002] The function of engine oil lines is to deliver engine oil, helping to lubricate and cool the various components of the engine, thereby ensuring the normal operation and performance of the vehicle. Engine oil lines are generally made of high-temperature and pressure-resistant materials, such as rubber, steel, or composite materials. The interior of the oil lines is usually smooth to reduce resistance to oil flow, thereby improving lubrication.

[0003] Before assembly, engine oil pipes need to be bent into a shape suitable for the vehicle model using a bending machine. When bending the oil pipes, the appropriate bending method is selected based on the material properties of the pipe itself, generally including cold bending, hot bending, and CNC bending. Currently, the most commonly used oil pipes are made of metal alloys, typically bent using a pipe bending machine, suitable for rapid mass production. Although current pipe bending machines, under system settings, can automatically perform multiple bends in one go and can bend at multiple angles in three dimensions, many machines still require significant manual intervention or auxiliary operations in the loading, unloading, and positioning and clamping of the oil pipes. For example, manual placement of workpieces, initiation of the positioning and clamping program, and manual removal of finished products are all required. This frequent manual intervention before and after the bending process not only restricts further improvement in production efficiency but also increases the labor intensity of operators, especially in scenarios requiring high-speed, large-scale continuous production. Therefore, we propose an engine turbocharger return oil pipe bending and forming processing equipment to solve the aforementioned problems. Summary of the Invention

[0004] In view of this, in order to solve the problems of traditional bending equipment requiring manual assistance for loading and unloading throughout the entire process, which is not only time-consuming and labor-intensive, but also has low work efficiency, and long-term cyclical operation will greatly increase the fatigue of workers, as well as low degree of automation, this invention provides an engine turbocharger return oil pipe bending and forming processing equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an engine turbocharger return oil pipe bending and forming processing equipment, including a worktable, with support legs fixedly connected to the four corners of the bottom of the worktable, and further including:

[0006] The L-shaped mounting bracket is fixedly connected to the top side of the workbench surface;

[0007] A sliding seat is slidably disposed at the bottom of the L-shaped mounting bracket, and the L-shaped mounting bracket is provided with a drive mechanism for driving the sliding seat to move back and forth;

[0008] A bending mechanism is located on one side of the top of the worktable and is used to bend and shape the oil pipe.

[0009] The positioning mechanism is located above the worktable and connected to the bending mechanism. It is used for positioning and supporting the oil pipe. The positioning mechanism works in conjunction with the sliding seat to automatically clamp the oil pipe and simultaneously bend and transport it.

[0010] Furthermore, the drive mechanism includes a lead screw motor fixedly connected to one side of the L-shaped mounting bracket. A fixing block is fixedly connected to one side of the bottom of the L-shaped mounting bracket. The fixing block and the L-shaped mounting bracket are rotatably connected to the same lead screw. A sliding seat is threaded onto the lead screw. The output shaft of the lead screw motor rotates through one side of the L-shaped mounting bracket and is fixedly connected to one end of the lead screw.

[0011] Furthermore, the bending mechanism includes a positioning post that penetrates the top of the workbench. The bottom end of the positioning post extends downward and is fixedly connected to a base plate, which is connected to the workbench. A sleeve that movably penetrates the top of the workbench is movably fitted on the outer wall of the positioning post. A bending rod that works with the positioning post is fixedly connected to the top of the sleeve. A driving component for driving the sleeve to rotate and move up and down is provided on the workbench.

[0012] Furthermore, the driving component includes a servo motor and a second cylinder fixedly connected to the top of the worktable. The output shaft of the servo motor rotates through the bottom of the worktable and is fixedly fitted with a long gear. An external gear plate that meshes with the long gear is fixedly fitted on the outer wall of the sleeve located below the worktable. A lifting sleeve plate located below the external gear plate is rotatably fitted on the outer wall of the sleeve. The output end of the second cylinder passes through the bottom of the worktable and is fixedly connected to the top side of the lifting sleeve plate.

[0013] Furthermore, a triangular truncated pyramid is provided on one side of the top of the worktable, the top end of the sleeve passes through the top of the triangular truncated pyramid and has an inclined surface that is flush with the inclined surface of the triangular truncated pyramid, the top end of the positioning column extends to the top of the triangular truncated pyramid, and two first cylinders are symmetrically fixedly connected to the bottom of the worktable, and the output ends of the two first cylinders are fixedly connected to the top of the base plate.

[0014] Furthermore, a collection box for use with a tripod is placed on one side of the workbench.

[0015] Furthermore, two guide rods are symmetrically fixedly connected to the top of the lifting sleeve plate. The top ends of the two guide rods penetrate the top of the worktable and extend into the interior of the triangular truss. Two guide holes are symmetrically opened on the top of the triangular truss to be inserted and matched with the corresponding guide rods.

[0016] Furthermore, the positioning mechanism includes a vertical strip plate that is slidably connected to the top of the worktable. The bottom end of the vertical strip plate is fixedly connected to the top of the base plate. A horizontal strip plate is slidably connected to one side of the top of the vertical strip plate. A positioning seat that fits against one side of the vertical strip plate is fixedly connected to the side of the horizontal strip plate near the positioning column. The positioning seat and the positioning column cooperate to complete the positioning and placement of the oil pipe. The positioning seat and the sliding seat cooperate to complete the clamping and conveying of the oil pipe.

[0017] Furthermore, the horizontal and vertical strips are connected by a damped sliding connection. When the first cylinder is activated, it moves the base plate up and down, which in turn moves the positioning post and the vertical strips up and down synchronously, thereby moving the positioning seat up and down.

[0018] Furthermore, a positioning groove is provided on the top of the positioning seat, and two clamping blocks are symmetrically slidably connected inside the positioning groove. A first slide rod is fixedly connected to the side of the two clamping blocks that is far away from each other. The ends of the two first slide rods that are far away from each other pass through one side of the positioning seat and extend outward. A first spring is sleeved on the outer wall of the two first slide rods, and the two ends of the first spring are fixedly connected to the end of the first slide rod that is far away from the clamping block and the side of the positioning seat, respectively.

[0019] Furthermore, a positioning notch communicating with the positioning groove is provided on the top side of the positioning seat away from the vertical strip.

[0020] Furthermore, the bottom of the sliding seat has two symmetrical bottom grooves, each with a movable block inside. The bottom of each movable block has symmetrically arranged docking grooves. The inner walls of the two docking grooves on opposite sides have inclined surfaces. The tops of the two clamping blocks are fixedly connected with a stop block that cooperates with the inclined surface of the docking groove. The top walls of the two docking grooves have slots that cooperate with the corresponding stop blocks.

[0021] Furthermore, the sliding seat is provided with a limiting component that works in conjunction with the two movable blocks, and the limiting component intermittently abuts against the vertical strip.

[0022] Furthermore, the limiting component includes a cavity formed inside the sliding seat. A pull rod is slidably connected through the inner wall of the cavity on the side away from the movable block. A connector is fixedly connected to one end of the pull rod inside the cavity. Two L-shaped abutments are symmetrically fixedly connected to the outer wall of the connector. One end of each L-shaped abutment extends into two bottom grooves and abuts against the side of the two movable blocks away from each other. Symmetrically arranged triangular notches are formed on the top edge of the side of the two movable blocks near the cavity. One end of each L-shaped abutment intermittently abuts against the inclined surface of the corresponding triangular notch. Two second sliding rods are symmetrically fixedly connected to the side of the two movable blocks away from each other. The other ends of the four second sliding rods all penetrate through the corresponding side of the sliding seat and extend outward.

[0023] Furthermore, the end of the pull rod away from the connector extends outward and is fixedly connected to a limiting block that intermittently abuts against the vertical strip. A second spring is sleeved on the outer wall of one side of the pull rod inside the cavity, and the two ends of the second spring are fixedly connected to one side of the inner wall of the cavity and one side of the connector, respectively.

[0024] Furthermore, the elastic force of the second spring is less than that of the first spring.

[0025] The beneficial effects of this invention are as follows:

[0026] This invention, by setting up a positioning column and a positioning seat that move synchronously up and down, can work with a robotic arm to automatically position and place the oil pipe. As the positioning column and positioning seat move upward, they automatically align with a sliding seat, achieving automatic clamping and conveying of the oil pipe. Then, a bending mechanism bends the oil pipe. After the positioning column and positioning seat move downward, the top of the positioning column extends into the top of the casing, allowing the bent oil pipe to rest completely on the triangular platform, enabling it to automatically slide into a collection box for automatic unloading and collection. The entire process requires no manual operation for automatic loading, bending, and unloading of the oil pipe, improving automation, reducing manual labor intensity, and increasing overall processing efficiency.

[0040] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] Example 1: As Figures 1-5As shown, the engine turbocharger return oil pipe bending and forming processing equipment includes a worktable 1, an L-shaped mounting bracket 4, and a sliding seat 7. Support legs 2 are fixedly connected to the four bottom corners of the worktable 1. The L-shaped mounting bracket 4 is fixedly connected to one side of the top of the worktable 1. The sliding seat 7 is slidably connected to the bottom of the L-shaped mounting bracket 4. A lead screw motor 5 is fixedly connected to one side of the L-shaped mounting bracket 4. A fixing block 11 is fixedly connected to one side of the bottom of the L-shaped mounting bracket 4. The fixing block 11 and the L-shaped mounting bracket 4 are rotatably connected to the same lead screw 12, and the sliding seat 7 is threaded onto the lead screw 12. The output shaft of the lead screw motor 5 rotates through one side of the L-shaped mounting bracket 4 and is fixedly connected to one end of the lead screw 12. Starting the lead screw motor 5 drives the lead screw 12 to rotate, which in turn causes the sliding seat 7 to move back and forth at the bottom of the L-shaped mounting bracket 4.

[0042] The processing equipment also includes a bending mechanism located on one side of the top of the worktable 1 for bending and forming oil pipes. The bending mechanism includes a positioning post 8 penetrating the top of the worktable 1. The bottom end of the positioning post 8 extends downwards and is fixedly connected to a base plate 10, which is connected to the worktable 1. A sleeve 13, which movably penetrates the top of the worktable 1, is movably fitted onto the outer wall of the positioning post 8. A bending rod 17, which cooperates with the positioning post 8, is fixedly connected to the top of the sleeve 13. The worktable 1 is equipped with a driving component for rotating and adjusting the vertical movement of the sleeve 13. The oil pipe is positioned by the positioning post 8, and then the rotation of the sleeve 13 drives the bending rod 17 to rotate, thus achieving the bending and forming of the oil pipe. Simultaneously, by adjusting the vertical movement of the sleeve 13, it can cooperate with the positioning post 8 to achieve bending of the oil pipe in different directions, thereby improving the flexibility of bending and enabling bending and forming of oil pipes with different bending angles.

[0043] In one aspect of this embodiment, the driving component includes a servo motor 15 and a second cylinder 18 fixedly connected to the top of the worktable 1. The output shaft of the servo motor 15 rotatably passes through the bottom of the worktable 1 and is fixedly fitted with a long gear 21. An external gear disk 19 that meshes with the long gear 21 is fixedly fitted on the outer wall of the sleeve 13 located below the worktable 1. A lifting sleeve plate 16 located below the external gear disk 19 is rotatably fitted on the outer wall of the sleeve 13. The output end of the second cylinder 18 passes through the bottom of the worktable 1 and is fixedly connected to the top side of the lifting sleeve plate 16. When the servo motor 15 is started, the sleeve 13 can be driven to rotate within the lifting sleeve plate 16 through the meshing motion of the long gear 21 and the external gear disk 19. Since the oil pipe is positioned in the groove at the top of the positioning post 8, the sleeve 13 rotates and drives the bending rod 17 to rotate, and after contacting the oil pipe, the oil pipe is bent. In addition, both the servo motor 15 and the second cylinder 18 are set through the control system. When the oil pipe needs to be bent in the reverse direction, the second cylinder 18 is activated to drive the lifting sleeve 16 to move downward, which in turn drives the sleeve 13 to move downward, and at the same time drives the bending rod 17 to move downward, so that its top end is lower than the oil pipe. When the sleeve 13 moves downward, it also drives the external gear 19 to move downward. Since a long gear 21 is provided, the external gear 19 can always maintain a meshing state with the long gear 21. Therefore, after the sleeve 13 drives the bending rod 17 to move downward, the servo motor 15 is activated again, and the sleeve 13 drives the bending rod 17 to rotate to the other side of the oil pipe. After adjusting the position of the bending rod 17, the second cylinder 18 is activated again, and the lifting sleeve 16 drives the sleeve 13 to move upward, which in turn drives the bending rod 17 to move upward. Then, by activating the servo motor 15, the bending rod 17 is driven to rotate and move in the reverse direction, thereby achieving the effect of bending the oil pipe in the reverse direction.

[0044] This invention can be used in the field of bending and forming equipment for engine turbocharger return oil pipes, and can also be applied to other fields of this invention.

[0045] Example 2: This example is a further improvement on the previous example: as follows Figures 1-5 As shown, a triangular truss 6 is provided on one side of the top of the worktable 1. The top of the sleeve 13 passes through the top of the triangular truss 6 and has an inclined surface flush with the inclined surface of the triangular truss 6. The top of the positioning pin 8 extends to the top of the triangular truss 6. Two first cylinders 14 are symmetrically fixedly connected to the bottom of the worktable 1, and the output ends of the two first cylinders 14 are fixedly connected to the top of the base plate 10. A collection box 3 for use with the triangular truss 6 is placed on one side of the worktable 1. After the oil pipe is processed, the two first cylinders 14 can be activated to move the base plate 10 downward, which can move the positioning pin 8 downward inside the sleeve 13, as shown. Figure 10As shown, when the top of the positioning column 8 moves exactly inside the top of the sleeve 13, the first cylinder 14 stops working. At this time, the bent oil pipe will be completely on the inclined surface at the top of the triangular platform 6. Without any obstruction, the oil pipe will slide down the inclined surface under its own gravity and fall directly into the collection box 3 below for centralized collection, thus completing the automatic unloading and collection of the oil pipe without the need for manual unloading, reducing the labor intensity of manual labor.

[0046] In one aspect of this embodiment, two guide rods 20 are symmetrically fixedly connected to the top of the lifting sleeve 16. The top ends of both guide rods 20 penetrate the top of the worktable 1 and extend into the interior of the triangular platform 6. The top of the triangular platform 6 has two symmetrically formed guide holes 61 that engage with the corresponding guide rods 20. By limiting the sliding of the guide rods 20 within the guide holes 61, the stability of the lifting sleeve 16's vertical movement can be improved. In addition, by setting the two guide rods 20, the triangular platform 6 can be directly and movably mounted on the worktable 1 without additional fixing, ensuring stable use of the triangular platform 6 and facilitating disassembly of the triangular platform 6, thus improving the flexibility of use.

[0047] Example 3: This example is a further improvement on the previous example: as follows Figures 1-5As shown, the processing equipment also includes a positioning mechanism located above the worktable 1 and connected to the bending mechanism for positioning and supporting the oil pipe. The positioning mechanism works in conjunction with the sliding seat 7 to automatically clamp the oil pipe and simultaneously bend and transport it. The positioning mechanism includes a vertical strip 9 that slides through the top of the worktable 1. The bottom end of the vertical strip 9 is fixedly connected to the top of the base plate 10. A horizontal strip 27 is slidably connected to one side of the top of the vertical strip 9. A positioning seat 22, which is in contact with one side of the vertical strip 9, is fixedly connected to the side of the horizontal strip 27 near the positioning post 8. The positioning seat 22 and the positioning post 8 cooperate to position the oil pipe, and the positioning seat 22 and the sliding seat 7 cooperate to clamp and transport the oil pipe. The horizontal strip 27 and the vertical strip 9 are connected by a damped sliding connection. When the first cylinder 14 is activated, it moves the base plate 10 up and down, causing the positioning post 8 and the vertical strip 9 to move up and down synchronously, which in turn moves the positioning seat 22 up and down. When the positioning pin 8 moves downward to the top of the sleeve 13 and is in an unloading state, it will not obstruct the downward movement of the positioning seat 22. When the positioning seat 22 moves upward and docks with the sliding seat 7, the positioning pin 8 moves upward synchronously to ensure normal support of the oil pipe. When the positioning seat 22 docks with the sliding seat 7, it can automatically clamp and fix one end of the oil pipe, and start the lead screw motor 5 to drive the sliding seat 7 to move, which can simultaneously drive the positioning seat 22 to move, thereby driving the oil pipe to be conveyed and completed the bending. During the movement of the positioning seat 22, the horizontal bar 27 will slide within the vertical bar 9. Within the maximum stroke of the sliding seat 7, the horizontal bar 27 will not disengage from the sliding between it and the vertical bar 9, ensuring the stability of the movement of the positioning seat 22. At the same time, through the sliding cooperation between the horizontal bar 27 and the vertical bar 9, the positioning seat 22 can move up and down synchronously through the horizontal bar 27 during the up and down movement of the vertical bar 9. The damped sliding between the horizontal bar 27 and the vertical bar 9 ensures greater stability during the up-and-down movement of the positioning seat 22 driven by the vertical bar 9, preventing the positioning seat 22 from shifting and affecting the positioning of the oil pipe. Furthermore, to further enhance the stability of the positioning seat 22, in addition to damping measures, a magnetic attraction between a magnet and a metal block can be used to stably attach the positioning seat 22 to the vertical bar 9.

[0048] In one aspect of this embodiment, the top of the positioning seat 22 is provided with a positioning groove 221. Two clamping blocks 23 are symmetrically slidably connected inside the positioning groove 221. A first slide rod 24 is fixedly connected to the side of each clamping block 23 that is away from each other. The ends of the two first slide rods 24 that are away from each other pass through one side of the positioning seat 22 and extend outwards. A first spring 25 is sleeved on the outer wall of each first slide rod 24, and the two ends of the first spring 25 are fixedly connected to the end of the first slide rod 24 away from the clamping block 23 and the side of the positioning seat 22, respectively. A positioning notch 222 communicating with the positioning groove 221 is provided on the top side of the positioning seat 22 away from the vertical strip 9. Figure 1As shown, first adjust the height of the positioning seat 22 and the positioning column 8 to the loading state, that is, the positioning seat 22 is not in contact with the sliding seat 7, and the positioning column 8 is not fully extended into the top of the sleeve 13. At this time, the robot arm picks up an oil pipe from the material area and places it in the positioning notch 222 of the positioning seat 22 and the groove at the top of the positioning column 8. One end of the oil pipe is located in the positioning groove 221 and abuts against the inner wall of the positioning groove 221, thereby completing the positioning and support placement of the oil pipe.

[0049] Example 4: This example is a further improvement on the previous example: as follows Figures 1-8 As shown, the bottom of the sliding seat 7 has two symmetrically formed bottom grooves 71. Each bottom groove 71 contains a movable block 28. The bottom of each movable block 28 has symmetrically arranged docking grooves 281. The inner walls of the two docking grooves 281 on opposite sides have inclined surfaces. The tops of the two clamping blocks 23 are fixedly connected to a stop block 26 that mates with the inclined surfaces of the docking grooves 281. The top walls of the two docking grooves 281 have slots 282 that mate with the corresponding stop blocks 26. The sliding seat 7 contains a limiting component that mates with both movable blocks 28, and the limiting component intermittently abuts against the vertical strip 9. When the vertical plate 9 moves the positioning seat 22 upward, it simultaneously moves the clamping block 23 and the abutment block 26 upward. When the top of the abutment block 26 extends into the bottom groove 71, it also extends into the docking groove 281, initially contacting the inclined surface of the docking groove 281. As the positioning seat 22 continues to move upward, the abutment block 26 also continues to move upward with the inclined surface, simultaneously moving the clamping block 23 and causing the two clamping blocks 23 to move closer to each other. The clamping block 23 also moves the first sliding rod 24 and compresses the first spring 25. When the abutment block 26 aligns with the slot 282, the clamping and fixing of the oil pipe is complete. The abutment block 26 continues to move upward within the slot 282 until the engagement between the positioning seat 22 and the sliding seat 7 is completed. After the clamping is completed, the lead screw motor 5 is started to drive the lead screw 12 to rotate, which in turn drives the sliding seat 7 to move towards the positioning post 8. Then, the abutment block 26 can be fitted into the slot 282, and the moving block 28 can synchronously drive the positioning seat 22 to move, thereby completing the automatic clamping and conveying of the oil pipe. In order to facilitate the protection and clamping of the oil pipe, rubber pads can be set on the side of the two clamping blocks 23 that are close to each other.

[0050] In one aspect of this embodiment, the limiting component includes a cavity 72 formed inside the sliding seat 7. A pull rod 30 is slidably connected through the inner wall of the side of the cavity 72 away from the movable block 28. A connector 31 is fixedly connected to one end of the pull rod 30 inside the cavity 72. Two L-shaped abutments 32 are symmetrically fixedly connected to the outer wall of the connector 31. One end of each L-shaped abutment 32 extends into the two bottom grooves 71 and abuts against the side of the two movable blocks 28 away from each other. The top edge of the side of the two movable blocks 28 near the cavity 72 is provided with symmetrically arranged triangular notches 283. One end of each L-shaped abutment 32 intermittently abuts against the inclined surface of the corresponding triangular notch 283. Two second slide rods 29 are symmetrically fixedly connected to the side of the two movable blocks 28 away from each other. The other ends of the four second slide rods 29 all penetrate through the corresponding side of the sliding seat 7 and extend outward. The end of the pull rod 30 away from the connector 31 extends outward and is fixedly connected to a limiting block 34 that intermittently abuts against the vertical strip 9. A second spring 33 is sleeved on the outer wall of one side of the pull rod 30 located in the cavity 72, and the two ends of the second spring 33 are fixedly connected to one side of the inner wall of the cavity 72 and one side of the connector 31, respectively. The elastic force of the second spring 33 is less than that of the first spring 25. First, the movable block 28 is abutted by the L-shaped abutment rod 32, and in the abutting state, the side of the movable block 28 away from the second slide rod 29 abuts against the inner wall of the bottom groove 71, so that the movable block 28 is in a limited state in the bottom groove 71. During the abutment process of the abutment block 26 moving upward, the movable block 28 will not be moved, thus ensuring the normal clamping of the oil pipe. And during the process of the sliding seat 7 moving and driving the positioning seat 22 to move, the clamping of the oil pipe is always maintained. After the oil pipe is bent, the sliding seat 7 has not yet reached its maximum travel. The sliding seat 7, driven by the pull rod 30, causes the limiting block 34 to contact the top of the vertical plate 9 on the side furthest from the positioning seat 22. Then, the lead screw motor 5 can be started to move the sliding seat 7 a short distance further. During this movement, the limiting block 34 is stopped by the resistance of the vertical plate 9, thus keeping the pull rod 30 stationary. Simultaneously, the connector 31 and the two L-shaped abutments 32 also remain stationary. As the sliding seat 7 continues to move, the second spring 33 is compressed, and the two movable blocks 28 move with the sliding seat 7, disengaging from the limiting contact of the L-shaped abutments 32, placing one end of the L-shaped abutment 32 at the position corresponding to the triangular notch 283. At this point, under the elastic force of the first spring 25, the clamping block 23 will move to its reset position. Simultaneously, the movable block 28 will move through the abutment block 26, causing the two movable blocks 28 to move away from each other and one end of the L-shaped abutment rod 32 to contact the inclined surface of the triangular notch 283, thus achieving the effect of automatically releasing the clamp on the oil pipe. Then, the lead screw motor 5 will start again, driving the sliding seat 7 to move to its reset position, and simultaneously driving the positioning seat 22 to move to its reset position.After the sliding seat 7 and the positioning seat 22 are fully reset, the first cylinder 14 starts, driving the base plate 10 to move downwards. At the same time, it drives the positioning column 8, the vertical bar plate 9, and the positioning seat 22 to move downwards and into a unloading state, allowing the processed oil pipe to automatically slide down the inclined surface of the triangular platform 6 into the collection box 3. After the positioning seat 22 moves downwards, it also drives the clamping block 23 and the abutment block 26 to move downwards. Since the elastic force of the second spring 33 is less than that of the first spring 25, when the clamping of the oil pipe is released and the device is reset, it will not push the movable block 28 to move. Therefore, the oil pipe will not be clamped again, ensuring the normal reset operation of the entire device. After the abutment block 26 disengages from the movable block 28, the second spring 33 will cause the pull rod 30 to reset and move. The two L-shaped abutment rods 32 will move through the connector 31. By engaging with the inclined surface of the triangular notch 283, the two movable blocks 28 can be pushed closer to each other again. When the movable block 28 contacts the inner wall of the bottom groove 71 again, one end of the L-shaped abutment rod 32 will also contact one side of the movable block 28 again, thereby completing the automatic limiting of the movable block 28, which is convenient for the automatic clamping of the oil pipe in the next operation.
